RETAINING-WALL.

Specification of Letters Patent. Application filed September 26, 1913. Serial No.

Patented J line 9 1914..

To all whom it may concern: I

Be it known that. I, JOHN N. Prnnnnoon, a citizen .of the United States, residing at New York city, county of New York, and State of New York, have invented certain new and useful Improvements in Retaining- Walls, of which the following is a full. clear.

and exact description.

This invention is an improvement in bulkheads or retaining walls, more especially those constructed along water fronts, or

practical value,

. upon that of instalgreat horidue to the which under similar conditions lat-ion and use are Sub ected to zontal and vertical stresses,

. weightof the fill behind the wall, or heavy loads supported thereon.

In a patent to Maxwell 981,822, dated January 17, ing wall structure is M. Upso-n, No. 1911, a retaining wall, the individual piling units of which are relieved of horizontal loads by the cooperative action therewith of a horizontal beam maintained in position transversely along the top of the wall.

The invent on of the patent referred to is, essentially, a reinforced concrete structure, both the piling unit-s and the horizontal beam being composed of that material, and it has proved to be a construction of great being recognized among engineers as a standard type or form of construction for its intended purpose.

The inventiolrupon which this application for patient is based, is an improvement mary object of the present improvement be ing to secure the advantages and benefits of the said patented construction, but with a great saving of expense and of the time and labor involved in its installation.

the patent mentioned, the prishown. one element a of which comprlses a senes of pilingumts,

manufacture and installation. To avoid this necessity, as also those objections which ordinarily attach to the use of unprotected wooden piles, I employ, in lieu of interlocking concrete piling units, a relatively s aller number of suitable piles, preferably of wood, in combination with sections of concrete surrounding the same and which are adapted to interlock and form a substantially tight or continuous wall. In this way the requisite strength in the retaining wall to withstand both horizontal and vertical loads is secured, while by covering wooden piles with the concrete sections and extending the latter downfor a relatively short distance below the mud line, such piles are protected against the attacks of marine insects and indefinitely preserved.

The construction of my improved retaining wall and the manner of building the same, will be described in detail by reference to the accompanying drawings, in which- Figure 1 is a general sectional view,partly in elevation. of a retaining wall embodying the invention. Fig. 2. is a top plan view of the same, and Fig. 3 is a sectional view of a pile wit-h its surrounding protective concrete section.

All of the sections or units comprising the retaining wall, or such portions of the same as are below the water line, are formed in suitable molds and, preferably, of the same dimensions and materials. I make them each of the form of a slab A, integral with a body portion B, preferably on one side only of the slab, and through which. in those units designed to surround the piles, there is a circular opening of sufficient diameter to permit them. to be threaded over the piles G.

The edges of the slabs A may be formed or provided with suitable means to enable driven at the proper intervals to'permit the threaded over them concrete sections to be and to interlock with one another.

washing out the mud, or otherwise, the said sections are carried down below the normal bottom to a distancesufiicient to insure protection to'the piles from the attacks of marine insects. The piles are cutofi' at the top slightly .above the. mean low water level so as to remain saturated at all times, and

are surrounded to their top with the concrete sections.

- Above the tops of the piles proper, such additional concrete sections F as may be used to build up the wall to the desired ture and all other concrete parts employed in the structure are reinforced in the'usual and proper manner, and all individual sections,

molded or cast prior to their introduction into this structure, 'may be locked or bonded together in the manner usual in such cases, to secure better alinement, greater rigidity and the strength necessary to withstand lateral stresses.

The structure may be strengthened by the addition of buttresses .H, of any proper construction, but the details of such devices are not shown, aslthey may be of the usual char acterand they form in themselves no part of my present improvement.

It is manifest that the specific form of the sectional concrete units which make up the retaining wall may be greatly varied without departing from the invention, and that the special means for locking and interlocking t e same are not material.

What I claim is:

1. A retaining wall comprising, in combination, a series of wooden piles, sections of concrete surrounding said piles, and interlocking one with another, and concrete members forming an extension of the wall above the water line.

2. An element for retaining walls, comprising a slab and a hollow cylinder and'a wooden pile driven into the earth, said pile projecting throughsaid hollow cylinder.

3. A retaining wall comprising, in combination, a series of piles, sections of concrete surrounding said piles and interlocking one with another, and a horizontal beam along the upper portion of the wall adapted to relieve the individual piles of horizontal load.

4:. A retaining wall comprising, in combination, a series of wooden piles driven into the earth, a series of concrete sections each surrounding the portion of a wooden pile that projects between low water and the surface, each concrete section being extended laterally to contact with adjacent sections so as to form therewith an integral concrete structure.

5. A retaining wall comprising, in combination, a series of wooden piles driven into the earth, a series of concrete sections sub stantially T-shape in cross section, each surrounding the portion of a wooden pile that projects between low water and the surface, each concrete sectionbeing, extended laterally to contact with adjacent sections so as I to form therewith an integral concrete structure. v

6. A retaining wall comprising, in combination, a series of concrete members, 'each formed with a slab and a hollow cylinder and a series of wooden iles driven into the earth, each pile projecting through one of said hollow cylinders.

In testimony whereof I aflix my signature in the presence of two subscribing witnesses.
